Transparent Braces vs. Metal Braces: Cost Comparison — Which Is More Cost-Effective?

"Doctor, I want to get orthodontic treatment, but

it feels awkward to go to work with metal wires on my teeth...

But clear aligners also seem expensive, so which one should I choose?"

I’m Kim Tae-hyung, chief director of Blanche Dental Clinic.

When I see thousands of orthodontic patients, this question comes up all the time. If you search online, there’s an overwhelming amount of price information, and the more you compare, the more confusing it gets. Some posts say, "Metal braces are the best value," while others say, "Who even gets metal braces these days?"

As a dentist, I’ll be blunt: orthodontics is not something you decide based on "which is cheaper." If you choose an appliance that doesn’t fit your teeth and the treatment period gets extended by six months, the additional monthly fees can cost more than the money you saved on the appliance itself.

Today, to help prevent that kind of bad cycle in advance, I’ll explain it the same way I do in the treatment room.

Let’s start with the numbers, honestly

As of 2026, these are the average orthodontic costs in Seoul and the metropolitan area.

I’ll speak based on the total cost, including appliance fees, monthly fees, and retainers.

The exact amount can vary depending on your oral condition, but this is close to the actual market average.

Metal braces are in the 3.5 million to 4.5 million won range. They are the most traditional method and also the least expensive.

Ceramic braces cost 4.5 million to 5 million won, and self-ligating systems such as Clippy-C are in the 5 million won range.

Invisalign ranges from 1.5 million to 9.5 million won depending on the package, but for full treatment, the average is around 6.5 million won.

Domestic clear aligner brands cost around 2.5 million to 3.5 million won, which is lower than Invisalign, but their range of use is limited.

What many people overlook here is the monthly fee.

Orthodontic treatment usually lasts a year and a half to more than two years, with monthly visits for wire adjustments or appliance changes. These monthly fees generally accumulate at 30,000 to 70,000 won per visit. If you choose an appliance because it is cheaper, but the treatment period becomes six months longer, that means an extra 200,000 to 400,000 won in monthly fees alone.

It’s not just different appliances — the principles are different too

When I meet patients in the consultation room, many think clear aligners and metal braces are simply different in whether they are visible or not. In reality, the principle of moving teeth is completely different, so I usually explain it with examples.

Metal braces attach brackets to each tooth and connect them with wires. Put simply, it’s similar to placing a train on a railway track. The doctor can directly adjust the thickness and angle of the wire to move the teeth with precision. It is the method that offers the most accurate control for complex malocclusions or extraction cases.

Clear aligners, represented by Invisalign, simulate the overall movement plan using 3D software and then create step-by-step transparent appliances. The patient changes to a new aligner every 1 to 2 weeks to move the teeth little by little. They are removable and do not interfere with eating or brushing, but the patient must personally wear them for 20 to 22 hours a day.

The key point is this: depending on the type and severity of your malocclusion, the most efficient appliance changes completely.

"Expensive" does not mean better, and "cheap" does not mean a loss.

That’s why, as I mentioned at the beginning, orthodontics should not be decided simply by asking, "Which one is cheaper?"

If this is your case, consider metal braces.

After seeing orthodontic patients every week, my opinion as a dentist is that for protrusive mouth cases requiring extraction or cases accompanied by skeletal malocclusion, bracket-based orthodontics is overwhelmingly advantageous. When teeth need to be moved across a wide range, the continuous force provided by wires is much more effective.

Another case where brackets are safer is when patient compliance with wearing the appliance is a concern. Clear aligners are based on the assumption that they are worn 22 hours a day, but in reality, many people find it difficult to keep that perfectly for nearly two years. The longer the appliance is removed, the more the teeth tend to move back toward their original position, and the longer the treatment takes.

In cases such as the second-generation Clippy-C that we mainly use at Blanche Dental Clinic, the appliance is made of ceramic and uses a self-ligating system. Unlike conventional metal braces that tie the wire in place with elastic bands, this system fixes the wire with a sliding-door mechanism, which reduces friction, lessens discomfort, and tends to move teeth faster than ordinary braces. You can think of it as an appliance that preserves the precision of metal braces while improving aesthetics and convenience.

If this is your case, consider clear aligners.

Now let’s look at the opposite case.

In cases such as mild crowding, improving the alignment of the front teeth, or relapse after orthodontic treatment, Invisalign is very efficient.

If the range of tooth movement is not large, attaching brackets can itself be an excessive treatment.

For office workers, aesthetic concerns are also a very important factor. Especially for those with a lot of face-to-face work or frequent photo shoots, satisfaction with clear aligners can be much higher because it is hardly noticeable that they are undergoing orthodontic treatment.

However, there is one thing I definitely want to point out. "Invisalign" and "general clear aligners" belong to the same category, but they are completely different appliances.

Invisalign uses a patented material called SmartTrack and simulates the entire process with ClinCheck software. Compared with general clear aligners that are manually made in domestic dental labs, the elasticity of the material, fit, and range of application are different.

Expecting the results to be the same just because the cost is half can be risky.

Seeing it at a glance will help you understand much faster.

Appliance type	Total cost (average)	Average duration	Aesthetics	Pain	Suitable cases
Metal braces	3.5 million to 4.5 million won	1.5 to 2.5 years	Low (metal visible)	Some	Complex malocclusion, extraction cases
Clippy-C (self-ligating)	5 million won range	1 to 2 years	Moderate (ceramic material)	Relatively little	Precision comparable to metal braces + improved pain and duration
Invisalign	Average 6.5 million won	6 months to 2 years	High (almost invisible)	Relatively little	Mild to moderate malocclusion, emphasis on aesthetics
General clear aligners	2.5 million to 3.5 million won	6 months to 1 year	High	Relatively little	Limited to mild alignment improvement

※ The exact cost may vary depending on your oral condition, and the costs above are 2026 averages for Seoul and the metropolitan area, including appliance fees, monthly fees, and retainers.

If you only look at the numbers, metal braces seem cheapest and Invisalign seems most expensive,

but as I mentioned earlier, if you choose an appliance that doesn’t suit your case, the treatment period gets longer, monthly fees accumulate,

and in the worst case, you may even need to change appliances.

Please remember that the real 기준 for cost comparison is not the appliance price, but the total cost including the entire treatment period.

In the end, "benefit" comes after an accurate diagnosis

Of course, without 3D CT and intraoral scanner data, you cannot say which appliance is more beneficial based only on explanation or visual inspection.

In actual treatment, even teeth that look equally crooked can require completely different recommended appliances depending on root direction, bite condition, and whether there is a skeletal problem.

One thing I always tell patients is that orthodontics is done by diagnosis, not by the appliance. No matter how good the appliance is, if the diagnosis is wrong, the teeth move in the wrong direction, and you end up spending both time and money twice.

At Blanche Dental Clinic, an orthodontic specialist first performs a precise scan with the iTero digital intraoral scanner, then checks the expected post-treatment changes through 3D simulation before deciding on the appliance. We also provide more than an hour of consultation.

If you’re wondering which appliance is most efficient for your case and what the total cost will actually be, please feel free to leave a comment or call us. I’ll check it personally and give you the most honest answer.
